REAR RIFLE-SIGHT.

Specification of Letters Patent.

Patented Feb. 4, 1919.

Application filed February 3, 1917. Serial No. 146,417.

To all whom it may concern:

Be it known that I, HENRY RISER, a citizen of the United States, residing at Bonners Ferry, in the county of Boundary and State of Idaho, have invented certain new and useful, Improvements in Rear Rifle- Sights, of which the following is a specification.

My invention relates to an improvement in rear rifle sights and pertains more particularly to a sight havin g contrasting colors, so that the eye niore readily finds the front sight.

The object of the invention is to provide a sight which will avoid the present need of filing a notch in the rear sight with a portion of the front sight before the rifle is correctly alined, and to avoid the necessity for the use of the so-called peep or other notched sights in expert rifle work.

In the accompanying drawings, forming a part of the specification Figure 1 is a perspective view of the rifle showmg my improved rear sight in position.

Fig. 2 is an end elevation.

Fig. 3 is a top plan view of the sight.

Fig. 4 is an enlarged detailed perspective view of the sight proper.

Numeral 1 represents the rifle barrel, on the front end of which is afliXed the front sight 2 of the usual construction. Near the breech of the rifle is mounted the customary sight plate 3 having an upstanding portion 4 comprising the beveled supporting portions 5 and 6 which are adapted to receive and hold a sight '7, which is preferably made of ivory, although it is obvious that any other suitable material could be equally well inserted and utilized. This sight 7 has a mortise 8 cut in the convex surface 9 which is adapted to receive and hold a narrow strip 10, of a sharp contrast in color to the sight strip. The preferable combination is a white sight with a narrow black strip running vertically therethrough, as disclosed in the drawings. Any suitable mechanism for elevating the sight, such as the common notched construction 11, may be used. In operation, the front sight 2 can be readily found protruding above the white surface 7, because of the contrast between a dark front sight and the white rear sight which I prefer to use. The rifle is then manipu lated so that the front sight 2 forms a continuation of the vertical black strip 10 in the rear sight 7 and when this is done the rifle is properly alined. It is obvious that other contrasting colors might be utilized, such as to form the rear sight of black ivory with a vertical strip of white in the center thereof, which in reality would be a modified form of the preferred construction. It is equally obvious that the vertical strip might be painted upon the contrasting background equally Well as being an inserted portion. Hence I do not wish to be limited to the precise construction set forth, but

I claim 1. A sight for fire-arms comprising a plate having an upstanding portion, a sight of one color slidably interlocked therewith and having a groove or mortise vertically formed in its rear surface and a sight of contrasting color held in said groove or mortise.

2. A rear sight comprising a supporting portion having beveled edges, an inserted portion engaged and held by said beveled portion, said inserted portion having a mortise, and a beveled portion of a contrasting color received and held in said mortise.

In testimony whereof I afiix my signature.

HENRY RISER.
